Get multiple 1yr memberships on Black Friday...?

Since a 1yr membership is so cheap on Black Friday, couldn't you buy multiple cards for years of membership? Say you buy two for $60...that's like 10 dollars more than just a year for a whole extra year! I'm not sure but I think PS+ subscriptions don't start until you input the code so you could buy a bunch and save them long enough to last the whole PS4 life cycle and save a ton of money o.o

They stack fine. I was in a pawn shop last week and saw a copy of Black Ops 2 and bought it because it was only 8 bucks and then I got home and opened it there was a PS+ code inside for 1 year and I figured it had been used but nope! I'm good until 11/2015.

However I wouldn't be surprised if theres a ceiling where they stop stacking.

i read a while ago that the PS4 comes with 14 days of PS+. is that true? because, you know, i wanna be able to use my system, but i want to get 2 years of plus for $60 with the Gamestop black friday deal, and the 14 days would obviously last me until black friday.

Exactly! I also think that you actually get a month of free PS+ with the PS4 out of box. I saw it in the official unboxing video they just released today. Picture of what comes with PS4: http://i.imgur.com/Yw8rbci.jpg

It also seems that you get $10 in-store credit for PlayStation Store out-of-box!

This is my plan. I frock in love Black Friday. Last year when the error in targets ad had MS points (1600 point cards) for 9.99, I bought up 5 cards, 100 bucks of game content for 50 bucks. That was a steal deal.

On the PS store there is a separate PS+ section (you'll see it when you open the app), in there you can purchase a month, 3 month or annual sub. How much it will be depends on your territory, $50 in US I believe, $70 here in AUS.
